` Application liled Augustl, 1884. (No model.) I

To all whom it may concer-n: y

Be it known that I, HENRY S. LORD, of Hartford, in the county of Hartford and State of Connecticut, have invented a. new Improvement in Attachments for VVater-Supplyl Cocks; and I do hereby declare the.. following, when taken in'connection with accompanying draw- -ings and the letters of reference marked thereon, to be -a full, clear, and exact'description of the same, and which said drawings constitute part of this specification, and represent,

lnf I Figure l, a longitudinal section; Figs. 2. 3, andai, sections through the cock, showing the different positions of the plug in the working of the apparatus.

This invention relates to a valve arrangement for the-supply of water to wash-basins, closets, and other purposes. v

In the use of common faucets serious diffrculties arise from leaving .the valve Open to permit a continuous dow of water., Not only does this cause injury to buildings, but a serions waste of water, it being a common practice to leave the faucets open in freezing Weather. Attempts to overcome this diflieult-y havebeen made by providing self-closing faucets; but thisdoes not accomplish the' object, from the fact that i-t isan easy matter to apply some device tohold the faucet open. The object of my invention is an apparatus whereby only a certain quantity of water can pass through the faucetwithout some personal attendance; and the invention consists in a side of the piston and then to the other, and

.when turned in one direction for the supply will open to the opposite direction for the escape of water from the reverse side of the piston, the said piston provided with a cushion upon `itsopposite faces to come to au easy bearing withinf the cylinder as the piston appreaches thc respective ends of its stroke, and as more fully hereinafter described.

A represents the cylinder, its ends closed l by heads B C. In the head B is an opening,

a, and in thehead Calike opening, b. Around the openinga is a tubular projection, d, extending into the cylinder, and around the opening b is a like tubular extension, e.

TD is the piston, fitted to move freely in the cylinder from end to end. Centrally Onone side oi' the piston is a cushion, f. This may be of any flexible or elastic-material.l On. the reverse side, and in the center, is a like cushion, g, These cushions stand in line with the tubular extensions d e in the repective heads of the cylinder. Around the respective cushions isa tubular projection, h., the internal diameter of which is larger than the external diameter of the tubular extensions d e, and also somewhat shorter than the said extensions d e.

E is the shell of`a` two-way cock, F being the plug. the cylinder a pipe. G, leads to one opening, h', in the shell En From the opposite opening, b, in the cylinder, a like pipe,` H, leads jto an opening, t, diametrically opposite the opening h. At right anglesl to the Openingsh z' in the shell aretwo openings, Zand m, diarnetrically opposite each other, and so that said openings h 'i lm are equidistant from each other. Through the plug two passages,

n o, are made, one opening from thetwo quar- From the opening a in one end of ter-points and the other from 'two opposite quarter-points, in the usual manner fora twoway cock. The inletpipe I leads to the passage Z, L being the outlet from the opening m. A The plug F of the cock is arranged lto be turned in the usual manner-say by a lever, M. The distance on the periphery ofthe plug of the cock between the openings of .the pas sages n o is greater than the openings ti l m,

so that when the" plug stands with the `openings to the passages n o between the open- -ings in the shell, as seen in Fig. 2, there is no communication through the openings in the plug. This is the normal condition of the apparatus. Suppose, now, that Water be required through the ou-tlet L, and that the cylinder upon theiefehand side ofthe piston is sneu l to iiow through the pipe G and the passage nthe plug register with the passages to and from produced while theplug stands in t-hat `conrives at the'opposite end and takes'its seat upon the projection e, and there comes to a rest, and '35 open until the piston has traversed to the end water from the pipe Iwill iiow through the. 'pipe G and opening a to that side of the piswith Water. Now', it' the plugF be turned to the position seen in Fig. 3, so that the passage o registei'swithlthe opening i Z, and the passage n with the openings h m, water will iiow from the pipe I through thepipe H and openingb into the right-hand end of the cylinder and against the piston and under pressure/ will force the piston toward the opposite end of the cylinder, causing the watertherein to the outlet soi long as the valve stands in that condition,'or until all the water on the left-hand side of the piston shall have passed from the cylinder. Then the piston willconie to a rest on the projectiond, the cushion takbearing thereon, and so that, notwithstanding the fact that the passages through the cylinder, nofurther tlo'w of waterean-be dition.. Now, suppose the plug to beturned to the position seen in Fig. 4, where the passage nregsters-with the openings Zh', and thc'pass'- age o registers with the openings i m. The direction of the dow of water' is reversed, and the ton,causing pressure thereon to drivethe water which had` before passed into the cylinder out through the opening l1 and pipe H to the outlet, and' will so continue until the piston arso may continue', theplug being turned rst to'` onerdirectionand thento the other. Water may continue to be drawn; but if the cock remain` ofthe cylinder opposite that from which the inow comes, at that timethe owwill be arrested, lirrespective of the position of the plug of the cock; hence it is in ipossihle to draw at a single opening anything beyond thecontents ot' the cylinder upon that side of the piston from which-the diat't'is made.

The cushion on thel cylinder, combined with the internal projections on the heads of the cylinder, permits the piston to come to an easy bearing at the respective endsoffthe cylinder, lunder the pressure of water, so that it' the pressure be very great there will be no thumping when the piston comes to a stand, the

-strain or compression.

- 1.` The combination ot' the cylinder 4ing an opening, a, at oneend and b at the cushions yielding sufti'cient to prevent its instantaneous or positive arrest.

It is not material that the piston shall traverse from one end to the other in order t-o make the discharge,or, suppose the Water to be cut off .when the piston stands midway ot' the cylinder, then the Water may be drawn from either end; but no'more can-be drawn at one turning otgthe plug than happens to loe in the cylinder on that side of the piston from which the draft is made. Y p

The tubular an'ge h around the cushion bcing of less extent than the length of the tubular projections into the cylinder permits the respective cushions to yield until the ange shall strike the head ot' the pist-on, and when so resting the cushion is, relieved from further Iclaini- A, havpposite end, each of the openings constructed with an internal tubular projection, the;

The conibination'of the cylinderA, havling a central opening, a, at one end and b at vthe opposite end, the tubular projection eX- tending into the cylinder around each ot` said openings, the piston D, provided with a cushion upon opposite sides corresponding to said tubular'extension, and the piston constructed with Va tubular fiaugeph. around said cushion, less in length than thesaid tubular extension, a two-way cock with a passage leading therevto from the respective ends of the cylinder,

and an inlet and an -outletto andl from said cock, substantially as described.
